Straight friend trying to learn how to help a closeted gay frirnd

Straight guy here, figured I'd check in with you fellas and look for some advice. My friend, let's call him Jay, recently came out and told me he was gay. No worries, I've had other gay/lesbian friends and really, this isn't something I'd treat anyone differently over. I still love my bud.So Jay and I live and lead a lifestyle that isn't "necessarily" conducive to your community, in that we both live in a rather rural area, we work blue collar jobs, and we are both big gear heads. (I'm a Chevy guy, but he drives a Subaru. So fitting, right?) I am sort of a big brother type to him, so in a completely platonic way I have to hold his hand and push him through some things and this will probably be the same, he's pretty worried and a little bit scared about his revelation. How can i, as a friend, help him? I know he has gotten Grindr, and started talking to someone, but me and one other close mutual friend are the only ones who know. His family doesn't know, and they are cause for more worry (godamn Catholics), what can I do to help walk him into accepting himself? He doesn't seem happy, let alone accepting of himself and it hurts to watch him get ripped up inside. Please/thanks in advance, boys. Jay could use a little help and I could use a little help too
